WICHITA, Kan. (AP) _ Governor Sebelius is talking to the attorney general about possibly filing a lawsuit over a new state law expanding gambling, rather than waiting for opponents to challenge it.

The governor says she and Attorney General Paul Morrison may file a lawsuit over the expansion rather than waiting for opponents to challenge it. "We think that it's probably better for investors to know that this is a certainty before they begin to put together a business deal, and that the most expedited way to get that done might be to ask the attorney general to bring the challenge quickly and ask for an expedited review by the Supreme Court," said Governor Sebelius.

The new law that permits new casinos in four areas and slot machines at dog and horse tracks in three cities is expected to take effect April 19th, despite the threat of a lawsuit. An Indian tribe already operating a casino in northeast Kansas may sue to derail the law.

The expanded gambling bill is expected to reap $200 million a year in revenues that makes Kansas the only state to own resort casinos.

Sebelius has bill-signing ceremonies today in four communities that could become home to state-owned casino-and-hotel complexes. She's stopping in Wichita, Dodge City, Kansas City and Columbus.
